Why my Blender project is corrupt when I export it from Blender to Unity?

Hi everyone
I was creating the player of my game but when I exported it to unity it was corrupt. I searched but I didn’t found how to resolve it

Can somebody help me?

Blender:


Unity:

I believe you have other materials with the same name as this .blend’s you’re importing. I already had that issue.

Just change the name of the materials in the .blend and you should be good to go.

You should put a proper name by default to keep things organized.
